Description
Technical field
The utility model relates to a kind of warm-up mill, particularly a kind of electromagnetic induction heating roller arrangement.
Background technology
Chinese patent application (patent) number: CN200810030777.7 discloses a kind of warm-up mill heating means and warm-up mill, the heating of warm-up mill is to heat by oil heating, steam heated, electric heating or Electromagnetic Heating mode, its characteristics are that warm-up mill is sandwich, be useful on the heat-conducting liquid medium of homogeneous heating roll temperature in the warm-up mill interlayer, warm-up mill roller outer surface is to heat with heat exchange pattern by the heat-conducting liquid medium in the warm-up mill interlayer.The warm-up mill structure that proposes is: a kind of warm-up mill, warm-up mill are sandwich, at the heat-conducting liquid medium that is useful on the homogeneous heating roll temperature in the warm-up mill interlayer.Described heat-conducting liquid medium can be that conduction oil, potassium sodium fusion melt the various heat-conducting liquid media such as metal, pure water, ethanol class material.
Although above-mentioned patent has obtained breakthrough achievement in electromagnetic induction heating roller roll body surface heating temperature homogeneity, in producing, practice has following shortcoming:
1, the interlayer of warm-up mill is that a steel closed structure, the interior heat carrier medium of interlayer expand in heating process, airtight interlayer internal pressure is raise, can force the heat carrier dielectric breakdown roll body in interlayer and produce and exosmose when pressure arrives certain value, have potential safety hazard.
2, the heat carrier medium in the roll body interlayer expands in heating process, and airtight interlayer internal pressure can raise, and after surpassing roll body and bearing pressure, can make the outer surface of roll body produce deformation, thereby the precision that affects equipment can not reach the requirement of production.
Chinese patent application (patent) number: CN 201110240976.2 discloses the warm-up mill that a kind of roller inside is provided with the high-frequency electromagnetic induction coil.Main body is the roll body of a hollow; Described roll body is built-in with conducting magnet core; One end of described conducting magnet core is by semiaxis stube cable connector; The described heater coil that twines outside having in conducting magnet core that draws in roll body by this cable connector; The described compensation heater coil that is entangled in the conducting magnet core two ends outside having that draws in roll body by cable connector; Be provided with one deck water-filling separate space in the roller wall of described roll body; Be respectively equipped with a plurality of ventilation holes that are used for heat extraction on the roll surface of described roll body both sides.Pressure after warm-up mill heating in the water-filling separate space can increase, and easily makes roll body generation deformation, affect equipment precision, thereby can not reach the requirement of production or make that roll body is destroyed and generation is exosmosed, and has potential safety hazard.
Therefore, the utility model provides a kind of electromagnetic induction heating roller arrangement, to solve the above-mentioned existing problem that exists.
The utility model content
The purpose of this utility model is to provide a kind of electromagnetic induction heating roller arrangement, to solve the above-mentioned problems that exist, guarantees that roll body is not destroyed, and guarantees the production precision, reaches and produces satisfactory product.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of electromagnetic induction heating roller arrangement comprises roll body, is provided with central shaft in roll body, and around electromagnetic induction coil, described electromagnetic induction coil is connected with the electromagnetic heating controller of roll body outside in the outer felt of central shaft; The inside of described roll body also is provided with airtight interlayer, it is characterized in that, is provided with safety relief valve on described interlayer.
In an embodiment of the present utility model, described safety relief valve is arranged on roll body and with interlayer and communicates.
Further, described safety relief valve is arranged on the right side of roll body.
In an embodiment of the present utility model, be provided with magnetic masking layer between described central shaft and electromagnetic induction coil.
In an embodiment of the present utility model, described safety relief valve is adjustable automatic safe relief valve.
The beneficial effect of a kind of electromagnetic induction heating roller arrangement of the present utility model is:
1, because interlayer is connected with safety relief valve, after heat carrier medium expanded by heating in interlayer, volume increases, airtight interlayer internal pressure can raise, during the safe pressure value set greater than adjustable safety relief valve when pressure, little the opening of safety relief valve opened pressure release automatically, and when airtight interlayer internal pressure dropped to the safe pressure value of adjustable safety relief valve setting, safety valve is autoshutdown again; So all the time, make interlayer pressure as within remaining on safe pressure value scope eventually, can guarantee that heat carrier medium in interlayer can not destroy roll body and produces and exosmose.
2, can be discharged when the superpressure due to airtight interlayer internal pressure, can not make the outer surface of roll body produce deformation, the useful life of greatly having improved Electromechanic heating roller in the safety in utilization that guarantees Electromechanic heating roller.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better execution mode of this case and be obtained to be well understood to.
Description of drawings
Fig. 1 is the structural representation of a kind of electromagnetic induction heating roller arrangement of the present utility model;
Fig. 2 is generalized section.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, further set forth the utility model below in conjunction with specific embodiment.
As depicted in figs. 1 and 2, a kind of electromagnetic induction heating roller arrangement of the present utility model, comprise roll body 10, described roll body 10 is metal material, be provided with central shaft 20 in roll body, around electromagnetic induction coil 30, be provided with magnetic masking layer 40 in the outer felt of central shaft 20 between described central shaft 20 and electromagnetic induction coil 30.Described electromagnetic induction coil 30 is connected with the electromagnetic heating controller 70 of roll body 10 outsides; The inside of described roll body 10 also is provided with airtight interlayer 50, is provided with safety relief valve 60 on described interlayer.
